A pair of shoes cost $22.99 to make, the local store sells them for $36.99. What is the percent markup? (Round to the nearest hu

ASHA 777 [7]

C: 60.9% is the right answer

Step-by-step explanation:

The markup is calculated by using the formula

$Mark\ up=Selling\ price-make\ price$

Given

Make Price = $22.99

Selling Price = $36.99

So the mark up will be:

$Mark\ up=36.99-22.99\\=\$14$

Percent mark up will be:

$Mark\ up=\frac{Mark\ up}{Make\ price}*100\\=\frac{14}{22.99}*100\\=0.6089*100\\=60.89\%$

Rounding off to the nearest hundredth percent

60.9%

Hence,

C: 60.9% is the right answer

Sean read 15 of a book in 112 hours.

makvit [3.9K]

Sean read 15 of a book in = 112 hours,
so, 1 of a book in = 112/15

Now, 12 of a book would be: 112/15 * 12 = 112/5 * 4 = 89.6

89.6 = 89 6/10 = 89 3/5

In short, Your Answer would be 89 3/5 hours

Hope this helps!
